This report from US News and World Report is worrisome. What do automotive tire safety ratings have to do with national security? Apparently someone thinks that they are related, since the tire safety data is now no longer available to the public. Neither is some public drinking water-quality data.
I haven't read the whole article yet, available here, but I will. Here's an excerpt from the summary:
New administrative initiatives have effectively placed off limits critical health and safety information potentially affecting millions of Americans. The information includes data on quality and vulnerability of drinking-water supplies, potential chemical hazards in communities, and safety of airline travel and others forms of transportation.
New administration policies have thwarted the ability of Congress to exercise its constitutional authority to monitor the executive branch and, in some cases, even to obtain basic information about its actions.
If true, this is what I would generally call "Not a Good Thing."
